suppose that 9% of the teachers at a university attended a conference. If 450 teachers attended the conference, how many teachers are at the university?

Question

algebra 2

Answer 1

If we let x stand in for the total number of teachers at the university and turn the 9% into a decimal, 0.09, we can write the equation:

                       0.09x=450

 

Then divide both sides by 0.09.

 

The result is that x=5000

Therefore there are 5000 teachers at the university.
